How to change default charset

How do I make charset default to UTF-8 for everything? Right now, the universal reader and writer default to ISO-8890-1.

Default charset is defined by default properties:

DataParser.DEFAULT_CHARSET_DECODER - for Readers
DataFormatter.DEFAULT_CHARSET_ENCODER - for Writers

The properties can be overridden in defaultProperties file or the new file, with these properties only, can be created and graph need to be run with -config switch (see Changing Default CloverETL Settings for full information).
